Recommended Action
Verify that the power supply is plugged in firmly. If
that does not resolve the issue, replace the power
supply. If the problem persists, replace the router.
Follow these steps to connect the PC or terminal to
the router:
1. Verify that your PC or terminal emulation
software is configured to communicate with
the switch using hardware flow control.
2. Configure the baud rate and character format
of the PC or terminal to match these console
port default characteristics: 9600 baud, 8 data
bits, 1 stop bit, No parity.
3. Using the supplied rollover cable, insert the
RJ-45 connector into the console port.
4. Attach the supplied RJ-45-to-DB-9 female
DTE adapter to a PC, or attach an appropriate
adapter to the terminal.
5. Insert the other end of the supplied rollover
cable in the attached adapter.
6. Run the terminal emulation program if you are
using a PC or a terminal.
If that doesn't help, verify that the equipment used
for connecting to the console is operating properly.
You can do this by connecting to a known good
router to check your console equipment. If the
equipment is successfully tested, but the problem
remains, replace the router.
The memory may not be well-seated. First, try to
reseat (remove and then re-insert) the Dynamic RAM
(DRAM) single inline memory module (SIMM)
memory. If the router still does not boot, replace the
router.
You can find information on the location of the
DRAM SIMMs in the
Cisco 1700 Series Routers
Documentation.
Set the configuration register to 0x2102 and reload
the router:
rommon 1 > confreg 0x2102
